Step 1: Understand what a binary search tree (BST) is. A BST is a tree structure where each node has a value, and the left child has a smaller value while the right child has a larger value.
Step 2: Learn about tree height. The height of a tree is the number of edges on the longest path from the root to a leaf.
Step 3: Know what balancing means. In a tree, balancing means keeping the heights of the left and right subtrees similar so that the tree does not become too lopsided.
Step 4: Discover what an AVL tree is. An AVL tree is a type of binary search tree that automatically keeps itself balanced.
Step 5: Understand the balance condition. In an AVL tree, the difference in height between the left and right subtrees of any node must be no more than one.
Step 6: Recognize the primary purpose. The main goal of an AVL tree is to ensure that the tree remains balanced, which allows for efficient searching, inserting, and deleting of nodes.
